To defeat a units’ contribution to the bus, turn the local Threshold and Attack all of the way up, and the Ratio all the way down.

Most compressor\/limiters use feedback to generate the sidechain signal. The control signal is always being modified by the action of the unit because of the previous signal. Feedforward operation uses the input audio to generate the sidechain signal, any previous operations do not have any influence on the operation of later signals. Very generally, feedforward is a faster, more aggressive operating mode, but it is easy to get too aggressive, especially with hot signals. Typically it is best to start working with a signal in the feedback mode, and then rotate the blend towards feedforward while readjusting the various sidechain controls to suit.

Most compressor\/limiters use feedback to generate the sidechain signal. The control signal is always being modified by the action of the unit because of the previous signal. Feedforward operation uses the input audio to generate the sidechain signal, any previous operations do not have any influence on the operation of later signals. Very generally, feedforward is a faster, more aggressive operating mode, but it is easy to get too aggressive, especially with hot signals. Typically it is best to start working with a signal in the feedback mode, and then rotate the blend towards feedforward while readjusting the various sidechain controls to suit.
